Loss of Power
Approximately 5 miles north of the airport, the pilot contacted the tower controller and reported losing power, stating he did not think he could reach the runway. The controller observed the airplane turn left, enter a nose-high attitude, and impact the water with the nose and left wing low.
Wreckage Examination
During the examination of the wreckage, water was drained from the right fuel tank and no fuel was present. The fuel selector was found selected to the right tank, and the fuel boost pump switch was broken. About 23 gallons of fuel was drained from the left fuel tank. Less than 1/2 ounce of water was found on the bottom of the left tank. There were no breaches found throughout the fuel system, and the fuel selector was free to move through all positions. The fuel supply lines were clear and unobstructed. Overall visual examination of the engine compartment and airframe did not reveal any evidence of fuel stains or fuel leakage. The fuel selector was disassembled and no leaks or discrepancies were observed.
